Miniature rose named Devclavel
BACKGROUND OF THE NEW PLANT 
     This miniature rose plant originated as a seedling of a hybrid produced by me at my nursery at Watsonville, Calif., as a result of my crossing the variety `Scarlet Sunblaze` with pollen of a unnamed seedling selected from rose plants maintained at my nursery for breeding purposes. The present seedling was selected for propagation because of its profuse production of relatively large blooms on a plant of ideal size for pot plant culture. Propagation of this selected seedling was done by me at Watsonville by means of cuttings and successive generations of this plant, all retaining the distinctive characteristics of the original seedling have demonstrated that the novel characteristics hold true and appeared to be firmly fixed. 
    
    
     DESCRIPTION OF THE DRAWING 
     My new miniature rose plant is illustrated by the accompanying photographic drawings which, in full color, show the novel characteristics of this plant, 
     FIG. 1 showing the top and bottom sides of a typical leaf and a series of buds in several stages of development terminating in a face view of a mature blossom; and 
     FIG. 2 is an elevational view of my miniature rose plant in full bloom and grown as a pot plant, the color rendition being as nearly true to that herein specified as is reasonably possible to obtain by conventional photographic procedures.
